Hi there,

Is there any way to get the transaction.id of the current transaction agent side ? (I specify a name for the transactions using apm.setTransactionName('myName))

The idea is to add the transaction.id to the logfiles so a specific transaction identified in the logfiles can be easily found in kibana.

Ok, forget me 🙂

Searching a little bit more, I found apm.\_instrumentation.currentTransaction.id (nodejs agent)  
I can use this to log the transaction ID.

You should use [`apm.currentTransaction`](https://www.elastic.co/guide/en/apm/agent/nodejs/current/agent-api.html#apm-current-transaction), so you don't go through the private `_instrumentation` property:

```auto
apm.currentTransaction.id

```

I just realized that we haven't documented the `id` property in the [transaction documentation](https://www.elastic.co/guide/en/apm/agent/nodejs/current/transaction-api.html) (we should do that), but you shouldn't expect the ID to be of a specific format, as we might change that soon. But it will remain a string.

Hi, thank you for the [`apm.currentTransaction`](https://www.elastic.co/guide/en/apm/agent/nodejs/current/agent-api.html#apm-current-transaction), I will use that, whaterver is the format as long it's a string.
